  CARTESIAN PRODUCT of the changes result set

• Effect of an additional table in the FROM clause in the query results?

  I recently helped a colleague debug one of their SQL statements
  
  The output was showing some very unexpected totals, and I was able to shrink down to an additional table in the FROM clause, but not used anywhere else in the application.
  
  Thus, for example
  
  SELECT A.ID, B.CODE
  Of
  EMPLOYEE,
  B OF THE STATUTE,
  PAY THE SAL
  WHERE A.ID = B.ID
  AND
  A.ID = 1;
  
  I was wondering, how can an extra table in a FROM clause influence directly on the rest of the query?
  
  The query above is just an example of what I've seen, the my co worker was working on is a bit larger and a lot more code to read. I noticed that when I added/removed the extra table in my query to co workers and then it worked as expected.
  
  I always thought that an additional table is not attached to what anyone would be just to do the inefficient code, but does not affect output

  just do the inefficient code

  Yes, that too, you will get a Cartesian product by calling is not the entries in the where clause for this table 'disappeared' :(

• Number of tables in the from clause

  Hello
  Can someone tell me how many tables can we have clause in oracle.

• Question on the use of expressions and aliases in the FROM clause

  Hello
  
  I have the following query
  

   select substr(e.ename, iter.pos, 1) as C
     from (select 'KING' as ename from dual) e,
          (select rownum as pos from dictionary where rownum <= 100) iter
    where iter.pos <= length(e.ename);

  outputs (of your choice):
  

  C
  -
  K
  I
  N
  G

  For the purposes of hardcode 'KING' was made for the test, IRL would be a column from other tables. Is the other piece that is hardcoded "where rownum < = 100 ' and it's the one I would like to find a way to remove.
  
  I tried the following:
  

   select substr(e.ename, iter.pos, 1) as C
     from (select 'KING' as ename from dual) e,
          (select rownum as pos from dictionary where rownum <= length(e.ename)) iter
    where iter.pos <= length(e.ename);

  Unfortunately this does not work because the SQL parser has not analyzed enough of the FROM clause to know e.ename causing the length (e.ename) expression return a message identifier unknown.
  
  I tried to restructure the query above to make the SQL parser aware of the e.ename early enough and therefore accept it. My efforts have failed.
  
  I would like to know if there is a way to restructure the statement length (e.ename) can be used instead of Hardcoding an artificial upper limit (for example 100 as in the first statement).
  
  Thank you
  
  John.

  Use CONNECT BY LEVEL:

  You can do this via an opaque view.

  You can also do this by modeling the cumulative value as a calculation LOGIC in the group by aggregation "pinned" to a specific dimension hierarchy that reflects consolidation in the online posting.

• Using a Bind Variable in the FROM of a SQL statement part?

  Hi all
  
  I have a problem, I am trying to execute a SQL statement. However, I need the FROM part of the SQL statement in a variable binding. This is because the end user will have to choose between 2 views of database.
  
  I tried this:
  Select CON_ID from: P23_DB_NAME where CON_LEGACY_ID =: P23_CONLEG_NO
  
  I had no chance. The error I got was,
  '+ The query cannot be parsed in the generator. If you believe that your request is
  syntactically correct, choose the generic "columns" box below the
  the source of the region without analysis.
  "ORA-00903: invalid table name +".
  What makes sence, but now I'm a little stuck.
  
  Does anyone have ideas for a workaround?
  
  Thanks in advance.
  -N.S.N.O.
  

  The example I gave you is quite simple. You must take some time to study it to see where you need to be very careful what put you where. Now, of course your example does not work becaues you have several errors. It will work for you:

  DECLARE
     x   VARCHAR2 (4000);
  BEGIN
     x := x || 'SELECT CON_ID FROM ';
     x := x || :p23_db_name;
     x := x || ' WHERE CON_LEGACY_ID = ' || :p23_conleg_no;
     RETURN (x);
  END;

• Session variable in the WHERE clause of the SQL statement

  Hey all,.

  I was wonering just if there is a way to set the WHERE clause of the query that the session variable?  I have the following so far and have tried to go through a ton of tutorials, but it doesn't seem to work.  Is it still possible?  I don't know what follows is wrong, but can someone help me with changing the following code, or pointing me to a good tutorial?  (I write it with PHP)

• How to put the subquery in the from clause

  Hi all
  
  I want to put a my from clause subquery. I want to show the details of an account, when the status is active, but I want to show the date when he opened.
  
  Here is my report query.
  
  Select t.acct_id, x.acct_status_Dt
  of cust_acct t, (select t1.acct_id, t1.acct_status_Dt from t1 cust_acct where t1.acct_status_code = 'OPEN') x
  where t.acct_id = x.acct_td
  and t.acct_status_code = 'ACTIVE'
  
  Someone knows how to impliment this kind of query in OBIEE without RPD Exchange.
  
  Help, please...

  Hello

  To be more clear, ask in the Advanced tab of the request, should look like:

  select A.saw_0, x.saw_1 from (select acct_id saw_0 from cust_acct)A, (select acct_id saw_0, acct_status_Dt saw_1 from cust_acct where cust_acct.acct_status_code='OPEN') x
  where a.saw_0=x.saw_0
  

  Actual query that you pasted:

  select t.acct_id,x.acct_status_Dt
  from cust_acct t , (select t1.acct_id, t1.acct_status_Dt from cust_acct t1 where t1.acct_status_code='OPEN') x
  where t.acct_id= x.acct_td
  and t.acct_status_code='ACTIVE'
  

  I think it is x.acct_id in where clause... not x.acct_td, I corrected and wrote the sql above...

  Now, we need to run an Insert...
  
  Insert into tableX (col1, col2,...) select a, b,... from < o/p of the cursor > where < blah >...
  Note: The table changes name and it the cursor can o/p emp, emp_a and emp_b.
  
  Trying to do at the same time instead of do series and with the best performance... .no sql injection issues.
  In parallel, I mean
  Insert into tableX (col1, col2,...) select a, b,... from emp where < blah >

  You do not HAVE a problem. You are just "assuming"; "Suppose that each query took 10 minutes... ».

  Well suppose that the time it takes to "chunk" the query, run it in parallel is longer than the time it takes to simply run the query. Oh, wait, that OF what you have discovered.

  Well, let's assume that each query took 2 seconds. Assume that all this takes that half a second. Suppose you waited until you actually have a problem.

  The solutions are to solve real problems, not imaginary and non-existent problems.

  If all you are doing is "assume that" you will never find a 'solution' because you could always 'suppose' another problem that prevents this 'solution' of work.

• Reference SQL Loader Bind Variables in the when Clause

  Support for SQL: SQL * Loader: version 8.0.6.3.0 (don't ask, it runs on Oracle EBS 11i...)
  
  I have a case where my sample data looks like:
  

  HD00100001002
  SM00100002CHAPS   99999999999                     20120906GBP0000000000001000000000001

  and another file
  

  HD00100001001
  SM00100002GBP0000000000001000000000001

  Essentially, I need to apply another "IN" clause for each record of SM depends on the ack_type (char 13 on HD recording), either 1 or 2
  
  I tried setting up the ack_type with a variable binding but find how to reference.
  
  Example of control file:
  

  --  $Header: test.ctl
  --
  
  LOAD DATA
  REPLACE
  
  -- Record Type HD : File Header
  INTO TABLE  test_table
  WHEN rec_id_no = 'HD'
  TRAILING NULLCOLS
  (rec_no                 RECNUM,
   hdr_line               CONSTANT 'H',

   file_number            POSITION(3:5)   CHAR,
   sequence_number        POSITION(6:10)  CHAR,
   status                 POSITION(11:12) CHAR,
   ack_type               POSITION(13:13) ":ack_type",
   co_id                  POSITION(14:21) CHAR,
   dept_id                POSITION(22:24) CHAR,
   btch_no                POSITION(25:36) CHAR,
   trans_id               POSITION(37:42) CHAR)
  
  -- Record Type SM : File Summary
  INTO TABLE test_table
  WHEN rec_id_no = 'SM' and :ack_type = '1'
  TRAILING NULLCOLS
  (rec_no                 RECNUM,
   hdr_line               CONSTANT 'L',
   rec_id_no              POSITION(1:2)   CHAR,

   amount                 POSITION(14:26) CHAR,
   number_trans_ok        POSITION(27:40) CHAR)

  The code above does not work, it is said that: ack_type is not recognized. Is there a way to do it, given the former character of the SQL Load version?

• Problems of execution of a SQL function with a variable in the WHERE clause

  Hello world!

  I have programmed a function that returns a boolean value based on the result of the SQL. It's the function:

  FUNCTION existe_secuencial (seq_name VARCHAR2) RETURN AS BOOLEAN

  cursor c2 is SELECT FROM all_sequences WHERE upper (sequence_name) = sequence_name' | seq_name | ' ;

  BEGIN

  OPEN c2;

  DBMS_OUTPUT. Put_line (nombre_seq);

  Get c2 INTO kk;

  If c2% NOTFOUND = True THEN

  RETURNS false;

  on the other

  RETURNS true;

  end if;

  END existe_secuencial;

  And I give the floor to the function of a procedure in this way:

  IF existe_secuencial ("SEQ_ARQUETA") = True THEN

  DBMS_OUTPUT. Put_line ('exists');

  ON THE OTHER

  DBMS_OUTPUT. Put_line ("' NOT exists");

  END IF;

  The probrem that this SQL is forced to return results because this sequence exists in the comic book, but is not, return me the FALSE value. What makes me mad is that if I change the second line of the function in this way:

  > > cursor c2 is SELECT FROM all_sequences WHERE upper (sequence_name) sequence_name ="SEQ_ARQUETA";

  It works find and return of sequence existing (real)

  Can someone help me please, I'm quite desperate to find what is the problem with that because I do not understand why if I built the slider with a variable returns no results so that if I do write it works...

  Thanks in advance!

  Itziar

  Frame you your variable in quotes, which makes the string literal ' |. ' seq_name | "rather than the content of the variable.

  I think that something like this would be an improvement.

  function existe_secuencial (seq_name VARCHAR2) return a Boolean value as

  number of exist_check: = 0;

  Start

  Start

  Select 1

  in exist_check

  of all_sequences

  where upper (sequence_name) = upper (seq_name);

  exception

  When no_data_found then

  null;

  end;

  return (exist_check = 1);

  end existe_secuencial;

• Sage line initialized the variable in the WHERE clause of another block of initialization

  Hello
  I have following problem.
  
  I created a block of initialization (called A) which initializes a wise session variable line.
  
  Ex: SELECT X, Y, z
  
  SELECT statement returns 3 rows (it is a block of initialization sage line!)
  
  So I want to create another block of initialization that uses in its cluase WHERE the sage variable line previous
  
  Ex: SELECT W, T of R where F = VALUEOF (NQ_SESSION. (A)
  
  I have the following error: DB2 - UDB: token SQL10104; was not valid, valuable chips:...
  
  I believe that this error is caused by the fact that VALUEOF (NQ_SESSION. (A) is translated by OBIEE inside (a list of values separated by; and not by).
  
  Can you suggest me a solution?
  
  Thank you
  
  Giancarlo
  
  P.S. I use OBIEE 10 G

  You can avoid this by rewriting it as

  t w, select
  r
  where f (with x = 'A' by selecting y in z)

  Kind regards

  change as follows:

   select UserLevel, v_login_chk into p_UserLevel,
          v_login_chk
  

  IN ONE ALONE is enough.

  BTW, don't you have "login Check" column in the "tbl_user"? If you do, your selection should be like this:

  ...
  select UserLevel, loginChk into /* check the column name in your table */
           p_UserLevel, v_login_chk
   from tbl_User
  ...
